STEAM WARPlNG-SCOW.

SPECIFICATION forming part of Letters Patent No. 454,632, dated June 23,1891.

Application filed December 31, 1890.

To all whom it; may concern:

Be it known that I, JOHN CEBURN WEST, machinist, of the town of Simcoe,in the county of Norfolk, in the Province of Ontario,

lowing is a specification.

by the stuffing-box J.

The object of the invention is to design a scow which may be propelledin water or on land, and provided with steam-d riven m echanism forpropelling it in the water, hauling it over the land, and warping orhauling logs and rafts; and it consists, essentially, of a scow providedwith steel-covered runners andcontaining an engine and boiler-connectedto mechanism, which with slight adjustment maybe directed to operate apair of paddle-wheels ora cable-winding drum, the boiler being carriedin suitable trunnions and provided with adjusting mechanism by which theangle of the boiler may be readily altered, the whole mechanism beingarranged substantially as hereinafter more particularly explained.

Figure 1 is a perspective view of my improved warping scow, one of thepaddlewheels being removed for the purpose of exposing the operatingmechanism contained in the scow. Fig. 2 is a cross-section of the scowwithout the mechanism.

In the drawings, A. is the scow, on the bottom of which twosteel-covered runners B are placed.

C. is the boiler, supported at its center in suitable trunnion-bearingsD.

E is a heavy arm securely riveted to the boiler C and designed to holdanutF, through which the adjusting-screw G passes. The bottom end of thescrew G is pivoted in and secured to the strap H, which is fastened tothe bottom of the scow. The steam pipe I is jointed,the said joint beingmade steam-tight This joint is made on a line with the center of thetrunnion D, so

'geared, as indicated, to the shaft L.

that the boiler C may be rocked on its trunnions without affecting thesteam-pipe. By arranging the boiler in this wayit may always be keptlevel, no matter how steep the hill the scow may be passing over.

K isa cable-winding drum suitably geared, as indicated, to theengine-shaft L.

M is a paddle-wheel shaft, which is also Shiftinghandles N are provided,so that either the drum K or the paddle-wheel shaft M may be connectedto or disconnected from the driving-shaft L.

I do not claim anything particular in the operating-gearing, as it maybe changed to suit the taste of the constructing engineer. The onlypoint to be observed is that the gearing must be strong in itsconstruction.

0 is a cable attached to the cable-winding drum K, which I connect tothe raft, and after anchoring or snubbin g the scow A, I throw themechanism into operation to wind the drum K. This cable, it will beobserved, passes be tween two friction-pulleys I, suitably journaled inthe frame Q, which is secured to the scowA by two staples R. This framemay be adjusted longitudinally, or, in other words, across the bow ofthe scow. An adjustingscrew S is provided for that purpose, or apawl-and-ratchet device may be substituted,

What I claim as my invention is- A scow provided with suitable engineand propelling means, a boiler C, pivoted on suitable trunnion-bearingsD in said scow, a jointed steam-pipe I, connected to saidtrunnion-bearings and engine, in combination with an arm E, connected tothe boiler, nut F, carried by said arm, and screw G, passing throughsaid nut, substantially as and for the purpose specified.

Simcoe, Canada, November 29, 1890.
